To will whom, it may condene; l

Be it known tlistl, HELDEN-D. JoNEs, citizen of the United. States, residing et Chi cago, Cook County, Illinois, lieve invented certain new and useful improvements' in Caroorv Hangers, of' uf'liioli the following isv aspeoiiiefition.

This invention relatesto hangers for sliderteins to that class of door-liangers in 'lii'oli .the spindles oic the track-rollers are ei'- -nnge'd sise to f 'oliwitiiinornpon suitable ways provided oy tlie henger itself.

Among Sine objects of v*die invent-ion are, to provide s eer-door henger that will operate with e niininiiun degree of frietion; to previde` s. onr- `oor hanger in Wliioli the box or heed witl'iiri which the rtrack-roller travels is formed with' (preferably integral) olosed ends 5 to provide n cendrier manger ot su struction. niiet tlie.door to Wliieli it is ettanned may travel freely iintil it arrives et s. eertziin disteneeiroin its fullyiopen or fully closed position zindwill then niovefless freely, thereby preventing the `usiiiil beng'ng ofrtlie cer door against its stops when tlieoiir is being' `sv-iiieiied about; and ingenerei, Vto pre-y vide e cendoor :hanger *of improved, ned, and eheapened oonsrnoton.

The invention eonsists in the matters here sinipliiiiafter described and .particularly pointed e iiioie .per,.loiigitiidinsilly slotted portion l in 'which Vtravels die eintiif'rietion track-.roller 2, end the downwardly extending loreeiiet portion 3 linvingtlie boltn'oles 'for reception of the bolts 5 by which the hanger is secured to ear door,` 6.' The 'hanger-heed, l, is @est ,in one piece and overliengs the lower portion. 'l in the usual iniinner. it is ioiined 'wien closed ends, T, connecting the iront vand rear sides l and l, as clearly shown in Fig. i.,

The traek-roller 2 is niade with en 'axial bore. When assembling tlie perte of the hanger, this roller is dropped into the need l from above. The mais of tlie roller is formed' by a roller-pin. S, which is of greater length ng doors, niore especially for freight eers-end nennen nfonns, onl oiilioeeo, iLLinois;

For the -reeeption of the proeoting endsoif f y with interior, longitudinal, pereliel find oppo-"i site grooves 9, between which tlie roller-pin 85 trevelsvfreely.

Z.bar,'and` is so arranged .that its web portion walls being provided with an opening located `6o to permit the insertion of the roller-pin forms the"track, 'one iiange depends at the outer' side of the track, andthe upper-,flange isfmade ofsuch` width that the heads 1 5 of lthe fastening-bolts 15 may lie principally l above the inner wall of the hanger-head, as

shown. 1 Round-headed or carriage-'bolts are better ada ted for this position thansquareheadedb ts. '.'The de endin flange ofthis track-bar performs a ouble unfction in the structure. In the 4irst place it constitutes aconiin'ingguard which prevents ythe top of the door from moving outwardly away from' the' side ofthe car, and prevents the rollers 2 (ofthe two hangers) from leaving their track-` "Secondly, said flange serves as a weathering strip, .which to a largev extent prevents the entrance oi dust, snow and moisture-ladenair into the car between the upper edge-.oi`

in the reduced ends of the grooves; As soon as thisbinding occurs, the rotation of the roller-pin 'willof coursel be arrested, and con sequentlythe further 'movement ofthe door.

in the same direction will'b'e impeded to 'a cer-v f' tain extent by the friction between the roller a'nd its f ixdpin as -it turns thereon. The reverse movement of "the 'door 'will cause the roller to disengage the from the tight ends loftheg'ro'oves..

Theend walls 7 of the hanger-head are so spaced from'the ends of the grooves 9 that when the roller vis at either end of its'travel it will be held out-'of contact with said end walls, hence will not be peripherally retarded .or braked asis thecase in a cpending application filed.
